cucumber依赖问题-无法加载插件类

Question

我是cucumber可扩展代码的新手，我需要帮助。我正在使用java 8和maven，并希望生成cucumber可扩展报告。但每次我得到以下错误：

cucumber.runtime.CucumberException: Couldn't load plugin class: com.cucumber.listener.ExtentCucumberFormatter. It does not implement cucumber.api.Plugin

Pom.xml文件是：

Runner类代码：

package runners;

import java.io.File;

import org.junit.AfterClass;
import org.junit.runner.RunWith;

import com.cucumber.listener.Reporter;

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(features = "src/test/resources/functionalTests", 
                 glue = { "stepDefinitions" },
                 plugin = {
        "com.cucumber.listener.ExtentCucumberFormatter:target/cucumber-reports/report.html" }, 
                 monochrome = true)
public class TestRunner {
    @AfterClass
    public static void writeExtentReport() {
        try {

                    Reporter.loadXMLConfig(new File("C:\\Software\\WprkSpace\\ExtendReport\\Configs\\extent-config.xml"));
        }
     catch (Exception e) {
        e.printStackTrace();
        }
        //Reporter.loadXMLConfig("/ExtendReport/Configs/extent-config.xml");
    }
}

我得到这个错误:

Answer 1

尝试将此 2 依赖项与以下相同版本一起使用：

<dependency>
    <groupId>com.vimalselvam</groupId>
    <artifactId>cucumber-extentsreport</artifactId>
    <version>3.0.2</version>
   </dependency>

    <dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports</artifactId>
    <version>3.1.2</version>
   </dependency>

用于cucumber的范围报告插件

Answer 2

POM分析说-

• 您保留不同的范围库以创建报告，这是不可取的

首先，让我们对创建数据块报告的这些库有一个基本的了解

1. Vimal Selvam库：下面是所需的maven依赖项和示例测试，以演示如何进行配置设置。

Maven Dependency

<dependency>
    <groupId>com.vimalselvam</groupId>
    <artifactId>cucumber-extentsreport</artifactId>
    <version>3.1.1</version>
</dependency>

请注意，Java 8和添加ExtentReport v3.1.1的依赖项是强制性的。为此，请将以下内容粘贴到pom.xml中：

<dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports</artifactId>
    <version>3.1.1</version>
</dependency>

cucumber流道文件

 @RunWith(Cucumber.class)
    @CucumberOptions(
            features = {"src/test/resources/features"},
            glue = {"com.cucumber.stepdefinitions"},
            plugin = {"com.cucumber.listener.ExtentCucumberFormatter:output/report.html"}
            )
    public class RunCukesTest {
        @AfterClass
        public static void teardown() {
            Reporter.loadXMLConfig(new File("src/test/resources/extent-config.xml"));
            Reporter.setSystemInfo("user", System.getProperty("user.name"));
            Reporter.setSystemInfo("os", "Mac OSX");
            Reporter.setTestRunnerOutput("Sample test runner output message");
        }
    }

上述设置将在输出目录中生成报告，名称为report.html.

2.范围适配器：美容是，您不需要编写任何代码来以这种方式生成报告，除了在下面的运行器中设置适配器。

Maven Dependency

<dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports-cucumber4-adapter</artifactId>
    <version>1.0.6</version>
</dependency>

将com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter插件添加到运行程序。

@RunWith(Cucumber.class)
@CucumberOptions(plugin = {"com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:"})
public class RunCukesTest {
    // ..
} 

报告输出目录-../Project Directory/test Output/HtmlReport

要点:我们不能直接混合

首先，您可以添加下面的cucumber最小依赖集。

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-junit</artifactId>
    <version>4.2.6</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-picocontainer</artifactId>
    <version>4.2.6</version>
    <scope>test</scope>
</dependency>

第二，考虑到不使用扩展适配器的情况，在POM.XML**下添加扩展依赖项。

<dependency>
    <groupId>com.vimalselvam</groupId>
    <artifactId>cucumber-extentsreport</artifactId>
    <version>3.1.1</version>
</dependency>

<dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports</artifactId>
    <version>3.1.5</version>
</dependency> 

在此工作流中，不要将com . avent stack . extent reports . cucumber . adapter . extentcuumberadapter插件添加到流道中。

作为最后一个 Hooks 类，我们编写针对每个场景执行的范围代码。

公共类钩子 {

private final static Logger log = Logger.getLogger(Hooks.class);
static volatile int x = 0;

@Before
public void setUpScenario(Scenario scenario){
    ExtentTestManager.startTest("Scenario No . " + (x = x + 1) + " : " + scenario.getName());
    ExtentTestManager.getTest().log(Status.INFO, "Scenario No . "+ x + " Started : - " + scenario.getName());
}

@After
public void afterScenario(Scenario scenario){
    String videoFile= Utility.stopAUTTestRecorder();
    try{
        if(scenario.isFailed()){
           ExtentTestManager.addScreenShotsOnFailure();
            //------------------------- Attaching video in the Report -------------------------
            String failedTestVideo = "<a href=\"" + videoFile + "\">Download Failed Test Case Video</a>";
            ExtentTestManager.embedVideoLink(failedTestVideo);
            //scenario.write(failedTestVideo);
        }
        }
        ExtentManager.getReporter().flush();
    }
  }
